Abstract

L'invention concerne une structure destinée au stockage de données dans une banque de données, ces données étant hiérarchisées par noeuds d'arborescence. Cette arborescence comprend un noeud-racine (1), si possible au moins un noeud intermédiaire (2, 3) et au moins un noeud terminal (4). Le noeud-racine (1) comprend au moins un élément-racine (1E); les noeuds intermédiaires respectifs (2, 3) comprennent au moins un élément intermédiaire (2E1, 2E2, 2E3,...) et les noeuds terminaux respectifs (4) comprennent au moins un élément terminal (4W1, 4E2, 4E3,...). Les éléments respectifs comprennent les données d'adresse nécessaires pour assurer la cohérence de l'arborescence et permettre des recherches dans l'arbre et les données. L'ordre des éléments dans un noeud correspond à un ordre logique des données -ordre numérique ou alphabétique -. Les données dans chaque élément respectif correspondent à la différence entre données par rapport aux données de l'élément précédent de la hiérarchie. Les données de l'élément racine constituent une valeur de départ. Cette valeur de départ correspond aux données courantes et les données différentielles des éléments restants sont constituées d'un mot de données qui représente la différence courante des données par rapport aux données de l'élément précédent, quelle que soit la différence entre données.
